To all whom it may 00mm;

I 7 Be it known that I, SYLvEsTna a citizen of the United States, residing at Springfield, in the parish of Livingston and State of Louisiana, have'inv'ented new and ,useful Improvements in Stump Removing and ClearingfMachines, ofwhich the following-is a specification: Q

' This invention relates to stump. removing and clearing machines, and is especially designed for cuttingor grinding away face of the ground, in order that the ground lowthesurface of the ground;

. are attained by the novel features of conmaybe properly cleared for ther lltivation of crops, and other desirablepurposes.

, i The prime'objectof-this inventionQ-is to providesimple, durable and eflicient means driven by any suitable or V fwhich will efl'eetually remove all stumps from the ground-to aj-suitable distancebe- A further object of the invention .is to provide revolving cutting or grinding means mounted upon a power driven truck, inconnection with means forautomatically-extending and withdrawing said.-revolving means, whichis adapted to ,cut or grind awaythe stumps by contact of the knives or :cutters with one'side of the stumps.

In carry ng outthis invention, the mech- 31118111 is prefenbly. mounted on amotor truck comprisinga frame 1, wheels2, and

tractor driving'wheels 3,'and suitably mount-v .ed on the frameis a four cylinder gasolene engine or other suitable motive'power 4, which is connected in any suitable manner with the driving shaft 5, and mounted on said shaft 5 at its outer end'i's a worm 6 which engages a worm gear (not shown) mounted on the shaft 7, the latter having mounted thereon a friction driving gear 8, adapted to engage the gears 9, carmounted a. cutting or grinding disk 16, said supported by onthe frame 1.

At the outer end portion of the screwthreaded end of theshaft 12, is mounted athreadcd nut 18 for the automatic feeding of the said shaft and disk 16 forwardly and rearwardly during the rotation of the shaft as will be readily understood, and ashaft 19 carrying a small driving friction gear 20 near one end, adapted to engage with the large driving pulley 8, and asmall friction gear 21 near the other end for frictional contact with the nut 18, so that'whenthe two pulleys 20* and21 are thrown apart they-will simultaneously engage the driving gear '8, and the thereby causing the disk} and shaft to be returned to theiriniti'al .position, since the shaft 12 and-"disk remain" right stem 26 and a rotatable wheel'27 for i raising and lowering the front portion of the machine.

" My improved cutter or disk 16 is mounted on the outer end of the shaft 12, and is provided with a one-quarter inch'steel plate *or disk 29; At 30 are illustrated radial arms that are mounted on the cutter 16. Ex-

tending a suitable distance beyond the face thereof, in staggered relation to the'circumferential area of the disk is a-series of cut- 7 ting tools 31, andsecured at the central portion of said disk is a conical shaped cutter 32 secured by suitable bolts and units 38,

while at intervals at the outer'peripheral portion of the disk is suitably and rigidly secured a-cutting tool 34:, said cutters being adapted to cut or grind away a stump toa distanceof twelve to fourteen inches below the surface of the ground when the disk is adjusted so that the cutters will contact with the side of the stumps, as will be readily obvious to those skilled in the art.

It will be perceived that the side I beams forming a portion of the frame 1, extend about six feet forwardly beyond the cutting or grinding disk, which in connection with the shaft carrying the disk, permits the said disk to travel six feet forward or rearward.

It will be seen that levers A, B and G are suitably. mounted so as to be within reach of the operator at the point X from which point the said levers may be readily manipulated. I would have it distinctly understood however, that the said levers and their mode of operation form no part of my invention, and hence any well known form or construction of levers maybeemploycdto throw the gears into and out of engagement with each other. However, in order to more clearly set forth the working of the gears when the levers are operated, I have deemed rt expedient to employ, for the purpose of illustration, the lever A being so mounted and connected as to throw the driving gear 8 into, engagement with the friction driving gears 9 thereby communicating a rotary motion to the gear 11, shaft 12, and the cutting or grinding disk 16, but when thegears 9' are thrown out of engagement and the shaft and 'disk'remain idle, and it is desired to bring the diskback to its initial working position, the lever B1 is: operated to throw the gears 20 and 21 apart and cause them 7 to simultaneously engage the driving gear 8, and nutlS, which action will cause the shaft and disk tobe returned ready to again begin work, while the lever O is so mounted that it operates a friction brake 35, which will cause the nut to remain still which pushes the shaft ahead, the nut and shaft being threaded, and the nut remaining stationary, the shaft is caused to revolve in and out or forwardly and rearwardly through the nut, as Will be readily understood;

The cutting disk is intended to cut or grind'to the-width of five feet six inches and twelve to fourteen inches below the surface of the ground, on the side of the stumps,

From the foregoing description. it is believed that the construction and operation of my improved stump remover will be fully understood by those skilled in the art to which the invention relates, hence it is thought that a more detailed description will not be necessary. 7

I-Ia'ving thus described my invention, what I claim and desire to secure by Letters-Patentis:-- I,
